PUMP.

. SPECIFICATION forming part of Letters Patent No. 299,373, dated May27, 1884-.

Application filed June 11, 1883.

To all whom it may concern.-

Be it known that I, JOHN J. GARDNER, a citizen of the United States,residing at North Madison, in the county of Jefferson and State ofIndiana, have invented certain new I and useful Improvements in Pumps;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional view. Fig. 2 is a sideview, and Fig. 3 is aplan view. r

This invention has relation to chain pump buckets; and it consists inthe. construction and novel arrangement of the common wire link,havi-ngopposite end loops twisted at relative right angles, the leather orrubber disk, and the upper and lower washers, said disk and washershaving central apertures of larger diameter than the link-wire, andadapted, when engaged therewith, to provide a drippassage, all ashereinafter set forth.

designates a link, having an upper loop, b, and a lower loop, 0, theends of the wire being secured to the middle of the link in forming theloops.

(1 represents a disk of leather or rubber, which is cut a little largerin diameter than the bore of the pump-tube, so that it will becomecrimped on the edge, as at 6, when A central aperture, 9, is cut in thedisk, said aperture being of larger diameter than that of the wire ofthe link a. h indicates a washer, having a central opening, it, oflarger diameter than the link-wire.

In constructing the bucket or pump-button, one loop of the link isopened out to enable the washer h to be placed on the middle portion ofthe link in contact with the inner portion of the other loop. Then therubber or (No model.)

leather disk is applied, and upon this another washer h, after whichthat end of the link which was opened out is closed up again in loopform, the wire end being forced into the central opening or eye of thesecond washer, so that all the parts are held firmly together.

In this manner a simple and durable pumpbucket can be readily andcheaply made by any mechanic.

The bucket will be found efficient in its operation, as the washers holdits middle portion firm, and its crimped edge fits closely to the wallof the pump-tube. The longitudinal openings in the disk and washersprovide a drip passage to prevent freezing. As the crimp of the bucketswill not allow them to move readily backward on the pump-tube, no latchor ratchet is required in connection with the pump-gear. The rubber orleather disk should be made of material of uniform thickness, and itwill have some elasticity or spring action at the crimped margin. Whenthe bucket is worn on the outside of its rim portion, it may be reversedand crimped in the other direction. In this manner it can be i made tolast twice as long as an ordinary In the accompanying drawings, theletter a single-surface bucket.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

The chain-pump bucket consisting of the wire link a, having a loop atopposite ends thereof twisted at right angles with relation to eachother, the rubber or leather disk thereon between the loops, and thewashers on each side of said disk, both washers and disk having centralapertures of larger diameter than the link-wire to provide adrip-passage, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN J. GARDNER.
